Abstract
BACKGROUND Andexanet alfa is a modified recombinant inactive factor Xa (FXa) designed to reverse FXa inhibitors. ANNEXA-4 (Andexanet Alfa, a Novel Antidote to the Anticoagulation Effects of Factor Xa Inhibitors) was a multicenter, prospective, phase-3b/4, single-group cohort study that evaluated andexanet alfa in patients with acute major bleeding. The results of the final analyses are presented. METHODS Patients with acute major bleeding within 18 hours of FXa inhibitor administration were enrolled. Co-primary end points were anti-FXa activity change from baseline during andexanet alfa treatment and excellent or good hemostatic efficacy, defined by a scale used in previous reversal studies, at 12 hours. The efficacy population included patients with baseline anti-FXa activity levels above predefined thresholds (≥75 ng/mL for apixaban and rivaroxaban, ≥40 ng/mL for edoxaban, and ≥0.25 IU/mL for enoxaparin; reported in the same units used for calibrators) who were adjudicated as meeting major bleeding criteria (modified International Society of Thrombosis and Haemostasis definition). The safety population included all patients. Major bleeding criteria, hemostatic efficacy, thrombotic events (stratified by occurring before or after restart of either prophylactic [ie, a lower dose, for prevention rather than treatment] or full-dose oral anticoagulation), and deaths were assessed by an independent adjudication committee. Median endogenous thrombin potential at baseline and across the follow-up period was a secondary outcome. RESULTS There were 479 patients enrolled (mean age, 78 years; 54% male, 86% White; 81% anticoagulated for atrial fibrillation at a median time of 11.4 hours since last dose, with 245 (51%) on apixaban, 176 (37%) on rivaroxaban, 36 (8%) on edoxaban, and 22 (5%) on enoxaparin. Bleeding was predominantly intracranial (n=331 [69%]) or gastrointestinal (n=109 [23%]). In evaluable apixaban patients (n=172), median anti-FXa activity decreased from 146.9 ng/mL to 10.0 ng/mL (reduction, 93% [95% CI, 94-93]); in rivaroxaban patients (n=132), it decreased from 214.6 ng/mL to 10.8 ng/mL (94% [95% CI, 95-93]); in edoxaban patients (n=28), it decreased from 121.1 ng/mL to 24.4 ng/mL (71% [95% CI, 82-65); and in enoxaparin patients (n=17), it decreased from 0.48 IU/mL to 0.11 IU/mL (75% [95% CI, 79-67]). Excellent or good hemostasis occurred in 274 of 342 evaluable patients (80% [95% CI, 75-84]). In the safety population, thrombotic events occurred in 50 patients (10%); in 16 patients, this occurred during treatment with prophylactic anticoagulation that began after the bleeding event. No thrombotic episodes occurred after oral anticoagulation restart. Specific to certain populations, reduction of anti-FXa activity from baseline to nadir significantly predicted hemostatic efficacy in patients with intracranial hemorrhage (area under the receiver operating characteristic curve, 0.62 [95% CI, 0.54-0.70]) and correlated with lower mortality in patients <75 years of age (adjusted P=0.022; unadjusted P=0.003). Median endogenous thrombin potential was within the normal range by the end of andexanet alfa bolus through 24 hours for all FXa inhibitors. CONCLUSIONS In patients with major bleeding associated with the use of FXa inhibitors, treatment with andexanet alfa reduced anti-FXa activity and was associated with good or excellent hemostatic efficacy in 80% of patients.

Abstract
Background Oral anticoagulation (OAC) is the mainstay of secondary prevention in ischemic stroke patients with atrial fibrillation (AF). However, in AF patients with large vessel occlusion stroke treated by endovascular therapy (ET) and acute carotid artery stenting (CAS), the optimal antithrombotic medication remains unclear.
Methods This is a subgroup analysis of the German Stroke Registry—Endovascular Treatment (GSR-ET), a prospective multicenter cohort of patients with large vessel occlusion stroke undergoing ET. Patients with AF and CAS during ET were included. We analyzed baseline and periprocedural characteristics, antithrombotic strategies and functional outcome at 90 days. Results Among 6635 patients in the registry, a total of 82 patients (1.2%, age 77.9 ± 8.0 years, 39% female) with AF and extracranial CAS during ET were included. Antithrombotic medication at admission, during ET, postprocedural and at discharge was highly variable and overall mortality in hospital (21%) and at 90 days (39%) was high. Among discharged patients (n = 65), most frequent antithrombotic regimes were dual antiplatelet therapy (DAPT, 37%), single APT + OAC (25%) and DAPT + OAC (20%). Comparing DAPT to single or dual APT + OAC, clinical characteristics at discharge were similar (median NIHSS 7.5 [interquartile range, 3–10.5] vs 7 [4–11], p = 0.73, mRS 4 [IQR 3–4] vs. 4 [IQR 3–5], p = 0.79), but 90-day mortality was higher without OAC (32 vs 4%, p = 0.02). Conclusions In AF patients who underwent ET and CAS, 90-day mortality was higher in patients not receiving OAC. Registration: https://www.clinicaltrials.gov; Unique identifier: NCT03356392.

Abstract
Ocean sediments consist mainly of calcium carbonate and organic matter (phytoplankton debris). Once subducted, some carbon is removed from the slab and returns to the atmosphere as CO2 in arc magmas. Its isotopic signature is thought to reflect the bulk fraction of inorganic (carbonate) and organic (graphitic) carbon in the sedimentary source. Here we challenge this assumption by experimentally investigating model sediments composed of 13C-CaCO3 + 12C-graphite interacting with water at pressure, temperature and redox conditions of an average slab–mantle interface beneath arcs. We show that oxidative dissolution of graphite is the main process controlling the production of CO2, and its isotopic composition reflects the CO2/CaCO3 rather than the bulk graphite/CaCO3 (i.e., organic/inorganic carbon) fraction. We provide a mathematical model to relate the arc CO2 isotopic signature with the fluid–rock ratios and the redox state in force in its subarc source. The carbon isotopic signature of CO2 released from marine sediments subducted beneath volcanic arcs does not reflect their organic/inorganic fraction, but instead the fluid-rock ratios and the redox conditions in force at the top of the slab.

Abstract
Aims
The aim of the study was to provide real–world data on low–density lipoprotein cholesterol (LDL–C) goal achievement at the time of current 2019 ESC/EAS Guidelines, treatment patterns and patient adherence to lowering lipid treatment (LLT).
Methods and Results
This community–based study identified patients with at least one LDL–C measurement and cardiological evaluation from 01–Jan–2016 to 31–Dec–2018. Patients risk stratification and LDL–C target achievement were assessed according to 2019 EAS/ESC guidelines. To identify the proportion of patients at LDL–C target, only patients with an available LDL–C evaluation after 1 year from baseline were considered (7317 patients, 51% of initial cohort 14317 pts). Of those, 492 pts (7%) presented LDL–C at target. Among them, 187 were at very high risk (4% of very high risk subgroup) and 47 at high risk (3% of high risk subgroup). Statin intolerance was reported in 7,5% of patients (1073 out of 14317). The adherence evaluation was performed in patients having 1–year of follow–up and at least one statin purchase. It was estimated through the Proportion of Days Covered (PDC), defining as adherent patients with a PDC value ≥ 75%. 8332 (58% of initial cohort 14317 pts) met the selection criteria for PDC calculation. Of those, 3346 (40%) patients resulted as adherent (46% and 22% in very high e high CV risk categories). In a multivariable Cox regression model, adjusted for age, sex, risk factors and comorbidities, patients adherence emerged as a protective factor (HR 0.62; 95% CI 0.43–0.89; p = 0,010).
Conclusion
In a real–world setting, the achievement of LDL–C target and patient adherence was suboptimal across different CV risk categories. In a full adjusted survival model, patient adherence was independently associated with a prognosis improvement.

Abstract
Abstract
Background
Lipid lowering treatment (LLT) and LDL–C target across CV risk categories might prompt consideration on further lower LDL–C levels advocated by last EAS/ESC guidelines.
Aim
The aim of the study was to provide current prevalence, clinical characteristics, LLT across different CV risk classes at the time of publication of current ESC/EAS Guidelines. Short–term prognosis was also addressed.
Methods and Results
This community–based study enrolled 6851 patients (mean age 71 years) with an LDL–C measurement and cardiological evaluation from 01–Jan–2018 until 31–Dec–2018. Of those, 4578 (67%) patients were at very high risk, 1494 (22%) at high risk, 420 (6%) at moderate risk, and 359 (5%) at low risk according to EAS/ESC 2019 guidelines. Dyslipidemia was present in three quarter of patients, and 3888 (57%) received LLT. High Efficacy (potency to reduce LDL–C ≥ 50%) LLT was prescribed in 21% of patients (23% and 10% in very high and high risk categories). There was a statistically significant difference between CV categories with respect to demographic, CV risk factors, and comorbidities. Patients at very high risk were more frequently elderly with a high proportion of patients affected by atherosclerotic CVD (ASCVD) and non–cardiac comorbidities. 394 (9%) patients at very high risk and 102 (7%) patients at high risk presented LDL–C at target. Among very high risk patients, 439 (10%) were treated with ezetimibe. At 24 months of follow–up, death occurred in 676 (8%) patients. In survival curves, adjusted for age and comorbidities, an increased risk of death and CV hospitalization was confirmed in the high risk and very high risk categories. Similar trend was confirmed considering composite endpoint of myocardial infarction and stroke.
Conclusion
In a contemporary population the strategy to achieve the ambitious LDL–C target of current Guidelines continue to be largely suboptimal and LLT is widely underused. This underlines the huge unmet need when assessed more aggressive LDL–C target advocated in current EAS/ESC guidelines.

Abstract
Abstract
Background
Secondary prevention after embolic stroke of undetermined source (ESUS) has not yet been established. ESUS is associated with high risk of recurrent ischemic stroke and clinically silent ischemic lesions. Secondary prevention with aspirin is the current standard therapy in ESUS patients, despite high prevalence of occult atrial fibrillation (AF).
Purpose
To determine whether the direct oral factor Xa inhibitor apixaban, started within 28 days after index stroke, is superior to aspirin in preventing new ischemic lesions in subjects with remote cardiac monitoring. Primary endpoint was detection of new ischemic lesions in flair and diffusion-weighted (DWI) MR imaging at 12 months follow-up.
Methods
The study enrolled ESUS patients with risk profile for cardiac thromboembolism (i.e., left atrium (LA) size >45 mm, spontaneous echo contrast in LA appendage, LA appendage flow velocity ≤0.2 cm/s, atrial high rate episodes, CHA2DS2-Vasc score ≥4, patent foramen ovale). Patients were randomized 1:1 into the aspirin and apixaban arms. Study drug was initiated within 3–28 days after minor/moderate stroke and 14–28 days after major stroke. MRI (Flair/DWI) was conducted within 7 days of AF detection by remote cardiac monitors and at 12 months. ClinicalTrials.gov Identifier: NCT02427126. Funding: The trial is supported by BMS-Pfizer Alliance.
Results
Enrollment was stopped after interims analysis (including 200 patients) due to futility. Overall, 373 patients were screened with 353 being enrolled (178 and 175 in apixaban and ASA arms, respectively). So far, 130 (73.0%) and 120 (68.6%) subjects from apixaban and ASA arms, respectively, completed the study. 2% death, 1.7% withdrawal, and 1.7% were lost to follow-up. 3.9% did not completed the study for other reasons. Mean age of the ATTICUS population was 68.5 years with 51% males. 80% of the subjects suffered from hypertension. Mean systolic blood pressure at enrollment was 132 mmHg, BMI was 27.7, and CHA2DS-VASc-Score was 4.9. So far, adverse events (AE) occurred in 63% of the subjects, 30% was documented as severe. 6.8% cases of recurrent ischemic stroke and no case of hemorrhagic stroke were reported. Only 1 case of severe bleeding was reported in the aspirin arm. Newly detected AF was reported in 80 patients (23%), 42 occurring in the aspirin arm. As required by protocol, latter were immediately switched from aspirin to apixaban. Due to ongoing data clearing, numbers and % will change until presentation.
Conclusions
In contrast to the recently published NAVIGATE and RESPECT ESUS trials, patients enrolled in ATTICUS need to exhibit additional AF predicting factors. Furthermore, mandatory cardiac remote monitoring will help to elucidate the impact of AF and the effects of early oral anticoagulation with apixaban compared to antiplatelet therapy with aspirin on the incidence of new ischemic lesions after ESUS. Preliminary data will be presented and discussed in the context of current literature.

Abstract
Abstract
In France, health public policies for people with disabilities are based on specific laws, recommendations and systems of reference. This population is under the responsibility of the medico-social sector, which governs specialized institutions and services. These services favor a medical approach to health focused on access to care. Their main missions are to take care of disabled people with kindness on a daily basis and to adapt the care to each person’s special needs, whatever the disability. They create links with families, organize the services offered and the living environments, administer their staff and collaborate with health professionals. As they ensure safety and health at all levels, from every individual project to collective life, they have a real opportunity to act on a set of health determinants.
The Ottawa Charter for Health Promotion refers to the empowerment and participation of the population as fundamental principles; this is also true as far as people with disabilities are concerned. With the principal stakeholders on a national level, we wrote a handbook in order to support the implementation of these principles in medico-social institutions and services: ’Promoting health and well-being in the medico-social field in cooperation with people with disabilities” and their families.
In this presentation, based on concrete examples, we will outline how the five intervention strategies of the Ottawa Charter can apply to people with disabilities, their families and their communities, especially inside specialized institutions and services. We will pay particular attention to the intervention methods and pedagogical tools which can be used to initiate or to improve the participation of disabled people in decisions, through the valuing of their experiential expertise, the development of their social skills, the strengthening of their health literacy, family-professional co-education, and cooperative strategies.
Key messages
Specialized institutions and services can promote the health of the people with disabilities they care for, by acting on the determinants of their health and by mobilizing participatory strategies. To strengthen disabled people’s participation, using their experiential expertise, developing their social skills and health literacy, and mobilizing co-education, are the best strategies.

Abstract
Abstract
Revacept is a novel lesion-specific inhibitor for platelet adhesion and thrombus formation. The biological drug is based on the platelet GPVI receptor and prevents collagen-mediated platelet activation from the atherosclerotic plaque. The unique characteristic of Revacept is the specific inhibition of plaque-mediated thrombus formation without alteration of hemostasis.
To test this concept in patients with plaque-mediated thrombosis we investigated patients with symptomatic carotid artery stenosis (at least 50% cf. ECST) with a recent ischemic cerebral stroke or transient ischemic attack (TIA). 150 patients were evenly randomized in blinded fashion to receive placebo, 40mg or 120 mg Revacept by IV infusion. To investigate anti-thrombotic efficacy, we assessed microemboli in the middle cerebral artery by transcranial Doppler (MES) and micro-infarctions in the brain by diffusion-weighted nuclear magnetic resonance (DWI-NMR) imaging. Ischemic complications such as myocardial infarctions and ischemic stroke were clinically followed up to 3 and 12 months. Bleeding complications were thoroughly monitored according to the RE-LY study group criteria. All patients were on standard anti-platelet therapy and underwent guideline conform treatment with carotid endarterectomy (CEA),carotid artery stent implantation or intensified conservative treatment.
The study was conducted in 16 centers in Germany and the UK from May 2013 to September 2018. Due to lost to follow-up investigations the planned patient numbers were slightly exceeded to 158 patients, who were finally included in the study according to intention to treat. Currently data clearance and detailed analysis of unblinded data is going on. 7.6% of patients underwent carotid artery stenting, 11.4% were under intensified conservative treatment and 81.0% were surgically treated with CEA. The safety data of the overall 158 patients which was closely monitored by an independent data safety board are available. In the overall study population (before unblinding for treatment) ischemic strokes and myocardial infarctions were numerically lower compared to previous studies with symptomatic carotid stenosis patients undergoing CEA or stenting (meta analysis from the EVA-3S, SPACE and ICSS study). Despite comparable basal anti-thrombotic therapy addition of Revacept did not increase bleeding complications in the overall study population.
The Revacept CS02 study has successfully achieved the aimed patient recruitment. Safety analysis shows a favorable profile. Bleeding complications in these high-risk patients with recent ischemic stroke were not increased compared to historic data from similar control patients. There is a trend for increased anti-thrombotic and anti-ischemic potency with regard to clinical events. Final data will be presented at the congress.

Abstract
PURPOSE To explore the association between patient-centered communication, patients' satisfaction, and retention in care in assisted reproductive technology (ART) visits. METHODS ART visits at eight Italian clinics were videotaped and coded using the Roter Interaction Analysis System, which includes a Patient-Centered Index (PCI), a summary "patient-centered communication" ratio. After the visit, patients completed a satisfaction questionnaire (SATQ). After 3 months, patients were asked about their retention in care. Spearman correlations and Mann-Whitney tests were used to test associations between the study variables; the open-ended item of SATQ was analyzed through content analysis. RESULTS Eighty-five visits were videotaped (involving 28 gynecologists and 160 patients). PCI score (μ = 0.51 ± 0.28) revealed a more disease-oriented communication during the visit. Patients reported high levels of satisfaction with the visit and identified in the information provision or in the doctor's humanity or kindness the main reasons of satisfaction. At the follow-up, the majority of the couples declared to have followed the clinicians' recommendations and to have remained related to the ART center. No associations were found among the study variables, except for a lower male satisfaction among couples who declared to have changed ART clinic. CONCLUSIONS Contrary to what was expected, the style of physician-patient communication was not found to be associated with patient satisfaction and retention in care. However, patients were highly satisfied and engaged. The actual meaning of a communication that is "patient-centered" in the ART context might be wider, including the couples' need for information, as suggested by qualitative findings.

Abstract
BACKGROUND AND PURPOSE Myeloproliferative neoplasms (MPNs) - polycythemia vera, essential thrombocythemia and primary myelofibrosis - are associated with increased risk for ischaemic cerebrovascular events (ICVEs). Due to their low prevalence, MPNs often remain undiagnosed as the cause of ICVEs. METHODS Case records at the University of Tübingen between 2014 and 2017 were screened to identify patients with MPN-related ICVEs. Clinical features, brain imaging, laboratory findings, applied treatments and neurological outcomes were assessed. RESULTS In all, 3318 patients with ICVEs were identified, and amongst them 17 patients with MPN-related ICVEs were included in a retrospective study. In 58% of these patients, ICVEs were the first manifestation of the underlying MPN; 24% presented with transient ischaemic attack and 76% with ischaemic stroke. Potentially concurrent ICVE etiologies were noted in 70% of the patients. The majority (94%) of patients were positive for the JAK2 V617F mutation, whilst in 29% recurrent ICVEs (range two to three) were noted prior to MPN diagnosis. Early MPN diagnosis and management was the only significant prognostic factor for ICVE recurrence (P < 0.001). DISCUSSION Evidence is provided that, although rare, MPNs represent an underdiagnosed cause of recurrent ICVEs. High clinical awareness is warranted to identify an underlying MPN in patients presenting with sustained, abnormal blood count findings. Clinical algorithms for prompt MPN diagnosis and initiation of MPN treatment (e.g. cytoreductive therapy, phlebotomy) are required. As MPN management comprises a significant protective factor against ICVE recurrence, induction of MPN treatment should be regarded as an integral component of secondary stroke prevention in MPN-associated ICVEs.

Abstract
Summary
Objectives:
Our objectives are: first to investigate the effects of internal cardioversion energies on the wave fronts propagation in the right atrium immediately after the energy delivery; second, to track the time course of these effects.
Methods:
The study is based on a measure of organization of the endoatrial electrograms obtained by a multipolar basket catheter inserted in the right atrium. We estimated the level of organization by computing the percentage of points laying on the signal baseline (i.e., number of occurrences, NO). NO values were computed on two-second long windows. Six non-overlapped windows were selected, one just before and five just after the last unsuccessful shock.
Results:
Immediately after the shock most of the patients exhibited an increase in the organization patterns. This increase was more evident in those patients with rather disorganized patterns and higher energy threshold. This effect fades within a few seconds after the shock delivery.
Conclusions:
Our data confirm the idea that the electrical shock causes a widespread extinction of electrical wavefronts, which regenerates after the shock. Since an increase of organization may lead to a reduction of energy threshold, a potential application of these findings might consist in the delivery of multiple subthreshold shocks instead of a single one.

Abstract
BACKGROUND During the last two decades major efforts in clinical research have led to the establishment of intravenous thrombolysis as the first line acute therapy for ischemic stroke. More recently, data from successful phase III trials have provided proof of the efficiency of mechanical recanalization in acute stroke. The fact that the efficiency of the available therapies can be increased through faster delivery is well documented; however, many institutions dealing with the emergency care of stroke patients lack organizational or infrastructural arrangements to optimize time efficiency in the diagnostic and therapeutic workup. CONCLUSION Many of these arrangements have been well evaluated, can be implemented at reasonable costs and have been proven to increase the beneficial effects of thrombolytic therapy.

Abstract
The resonant scattering and diffraction beamline P09 at PETRA III at DESY is equipped with a 14 T vertical field split-pair magnet. A helium-3 refrigerator is available that can be fitted inside the magnet's variable-temperature insert. Here the results of a series of experiments aimed at determining the beam conditions permitting operations with the He-3 insert are presented. By measuring the tetragonal-to-orthorhombic phase transition occurring at 2.1 K in the Jahn-Teller compound TmVO4, it is found that the photon flux at P09 must be attenuated down to 1.5 × 10(9) photons s(-1) for the sample to remain at temperatures below 800 mK. Despite such a reduction of the incident flux and the subsequent use of a Cu(111) analyzer, the resonant X-ray magnetic scattering signal at the Tm LIII absorption edge associated with the spin-density wave in TmNi2B2C below 1.5 K is intense enough to permit a complete study in magnetic field and at sub-Kelvin temperatures to be carried out.

Abstract
BACKGROUND AND PURPOSE The GABA(B) receptor agonist, baclofen, has shown promising effects in patients suffering from pain, post-traumatic stress disorder, alcoholism, overactive bladder and gastroesophageal reflux disease. However, baclofen's short duration of action and side effects limit its wider use. Here we characterized a novel, GABA(B) receptor positive allosteric modulator (PAM) ADX71943. EXPERIMENTAL APPROACH In vitro, ADX71943 was assessed for pharmacological activity and selectivity using recombinant and native GABA(B) receptors. In vivo ADX71943 was assessed in the acetic acid-induced writhing (AAW) test in mice and formalin tests (FTs) in mice and rats. Marble burying (MB) and elevated plus maze (EPM) tests, rotarod, spontaneous locomotor activity (sLMA) and body temperature (BT) tests in mice and rats were used to investigate centrally-mediated effects. KEY RESULTS In vitro, in the presence of GABA, ADX71943 increased the potency and efficacy of agonists and showed selectivity at the GABA(B) receptor. ADX71943 reduced pain-associated behaviours in AAW; an effect blocked by GABA(B) receptor antagonist CGP63360. ADX71943 reduced pain in the FT in mice and rats, but was inactive in the MB and EPM despite reaching high concentrations in plasma. ADX71943 had no effect on BT, rotarod and sLMA. CONCLUSIONS AND IMPLICATIONS ADX71943 showed consistent and target-related efficacy in tests of disorders that have a significant peripheral component (acute and chronic pain), while having no effect in those associated with centrally-mediated anxiety-like reactivity and side effects. Thus, ADX71943 is a useful pharmacological tool for delineation of peripherally- versus centrally-mediated effects of GABA(B) receptor activation.

Abstract
Early onset torsion dystonia (DYT1) is an autosomal dominantly inherited disorder caused by deletion in TOR1A gene. Evidence suggests that TOR1A mutation produces dystonia through an aberrant neuronal signalling within the striatum, where D2 dopamine receptors (D2R) produce an abnormal excitatory response in cholinergic interneurons (ChIs) in different models of DYT1 dystonia. The excitability of ChIs may be modulated by group I metabotropic glutamate receptor subtypes (mGlu1 and 5). We performed electrophysiological and calcium imaging recordings from ChIs of both knock-in mice heterozygous for Δ-torsinA (Tor1a(+/Δgag) mice) and transgenic mice overexpressing human torsinA (hMT1). We demonstrate that the novel negative allosteric modulator (NAM) of metabotropic glutamate 5 (mGlu) receptor, dipraglurant (ADX48621) counteracts the abnormal membrane responses and calcium rise induced either by the D2R agonist quinpirole or by caged dopamine (NPEC-Dopamine) in both models. These inhibitory effects were mimicked by two other well-characterized mGlu5 receptor antagonists, SIB1757 and MPEP, but not by mGlu1 antagonism. D2R and mGlu5 post-receptor signalling may converge on PI3K/Akt pathway. Interestingly, we found that the abnormal D2R response was prevented by the selective PI3K inhibitor, LY294002, whereas PLC and PKC inhibitors were both ineffective. Currently, no satisfactory pharmacological treatment is available for DYT1 dystonia patients. Our data show that negative modulation of mGlu5 receptors may counteract abnormal D2R responses, normalizing cholinergic cell excitability, by modulating the PI3K/Akt post-receptor pathway, thereby representing a novel potential treatment of DYT1 dystonia.

Abstract
BACKGROUND AND PURPOSE The GABAB receptor agonist baclofen reduces urethral resistance and detrusor overactivity in patients with spasticity. However, baclofen's side effects limit its use for the treatment of overactive bladder (OAB). Here, we tested a novel GABAB positive allosteric modulator (PAM) ADX71441 in models of OAB in mice and guinea pigs. EXPERIMENTAL APPROACH Mice were left untreated or given (p.o.) vehicle (1% CMC), ADX71441 (1, 3, 10 mg kg(-1) ) or oxybutynin (100 mg kg(-1) ; Experiment 1) or vehicle (1% CMC), baclofen (1, 3, 6 mg kg(-1) ) or oxybutynin (Experiment 2). Treated mice were then overhydrated with water, challenged with furosemide, before being placed into micturition chambers and monitored for urinary parameters. In anaesthetized guinea pigs, intravesical infusion of acetic acid was used to induce OAB and the effects of ADX71441 (1, 3 mg kg(-1) ) or baclofen (1 mg kg(-1) ), administered i.v., on cystometric parameters were monitored. KEY RESULTS In mice, 10 mg kg(-1) ADX71441 increased urinary latencies, reduced the number of urinary events and the total and average urinary volumes. In guinea pigs, ADX71441 (1 and 3 mg kg(-1) ) increased the intercontraction interval (ICI) and bladder capacity (BC), and reduced micturition frequency (MF) compared to vehicle. At 3 mg kg(-1) ADX71441 completely inhibited the micturition reflex and induced overflow incontinence in five out of 10 animals. Baclofen slightly increased ICI and BC and reduced MF. CONCLUSION AND IMPLICATIONS Our findings demonstrate, for the first time, that a GABAB PAM has potential as a novel approach for the treatment of OAB.

Abstract
The high magnetic field (HiFi) muon instrument at the ISIS pulsed neutron and muon source is a state-of-the-art spectrometer designed to provide applied magnetic fields up to 5 T for muon studies of condensed matter and molecular systems. The spectrometer is optimised for time-differential muon spin relaxation studies at a pulsed muon source. We describe the challenges involved in its design and construction, detailing, in particular, the magnet and detector performance. Commissioning experiments have been conducted and the results are presented to demonstrate the scientific capabilities of the new instrument.

Abstract
BACKGROUND The profile of patients with neurological diseases referred to specialized emergency rooms (ER) has not been reported and it is unknown whether a setting of decentralized ERs is associated with a high number of referrals because of inappropriate admissions. METHODS In this prospective study, consecutive patients of a specialized neurological ER were enrolled. Data encompassed time from symptom onset to admission, discharge diagnoses, data on hospitalization and on transfers to and from other ERs. RESULTS Thousand seven hundred and forty-three patients were enrolled. Most common diagnoses were cerebrovascular events (26.5%), headache disorders (13%) and seizures (12.7%). Time since onset of symptoms depended on who referred the patient (P<0.001); seizure patients presented earlier than other patients (P<0.001) and 30.5% of patients with cerebrovascular events presented within 3 h after symptom onset but did not present sooner than patients with other diagnoses. In 18%, diagnoses did not match neurological disorders, 4.5% of patients suffered from cardiovascular events. Referrals to and from other ERs rarely occurred (10.3% vs. 5.9%). Only 20 patients with acute cerebrovascular events were referred via other ERs (1.1%). CONCLUSION A system of a specialized neurological ER can quickly clear up uncertainties in interpreting neurological symptoms. Owing to the rising number of neurological patients in ERs, more studies are urgently needed comparing the different organizational forms for emergency services.

Abstract
We present numerical simulations of gate-all-around (GAA) 3C-SiC and Si nanowire (NW) field effect transistors (FETs) using a full quantum self-consistent Poisson-Schrödinger algorithm within the non-equilibrium Green's function (NEGF) formalism. A direct comparison between Si and 3C-SiC device performances sheds some light on the different transport properties of the two materials. Effective mobility extraction has been performed in a linear transport regime and both phonon- (PH) and surface-roughness-(SR) limited mobility values were computed. 3C-SiC FETs present stronger acoustic phonon scattering, due to a larger deformation potential, resulting in lower phonon-limited mobility values. Although Si NW devices reveal a slightly better electrostatic control compared to 3C-SiC ones, SR-limited mobility shows a slower degradation with increasing charge density for 3C-SiC devices. This implies that the difference between Si and 3C-SiC device mobility is reduced at large gate voltages. 3C-SiC nanowires, besides their advantages compared to silicon ones, present electrical transport properties that are comparable to the Si case.

Abstract
OBJECTIVES Our objectives are: first to investigate the effects of internal cardioversion energies on the wave fronts propagation in the right atrium immediately after the energy delivery; second, to track the time course of these effects. METHODS The study is based on a measure of organization of the endoatrial electrograms obtained by a multipolar basket catheter inserted in the right atrium. We estimated the level of organization by computing the percentage of points laying on the signal baseline (i.e., number of occurrences, NO). NO values were computed on two-second long windows. Six non-overlapped windows were selected, one just before and five just after the last unsuccessful shock. RESULTS Immediately after the shock most of the patients exhibited an increase in the organization patterns. This increase was more evident in those patients with rather disorganized patterns and higher energy threshold. This effect fades within a few seconds after the shock delivery. CONCLUSIONS Our data confirm the idea that the electrical shock causes a widespread extinction of electrical wavefronts, which regenerates after the shock. Since an increase of organization may lead to a reduction of energy threshold, a potential application of these findings might consist in the delivery of multiple subthreshold shocks instead of a single one.
